3d touch based user interface value pickers

ABSTRACT

Electronic devices that include a force sensor input and input user interface elements are described. The force sensors may be located to detect force on the display of the electronic device. The force sensor, alone or in combination with one or more other sensors such as capacitive touch sensors, allows for interaction with the user interface input on the device. By using a hold detection logic with a pressure level sensitive sensor, user interface elements can be manipulated or values can be assigned to input elements.

FIELD OF TECHNOLOGY

The present invention relates to the technical field of user interfaces.In particular, the invention relates to 3D touch based user interfaces.

BACKGROUND OF THE INVENTION

A large and growing population of users employs various electronicdevices to perform functions, such as placing telephone calls (voiceand/or video), sending and receiving email, text messaging, accessingthe internet, playing games, consuming digital content (e.g., music,movies, images, electronic books, etc.), and so on. Among theseelectronic devices are electronic book (eBook) reader devices, mobiletelephones, desktop computers, portable media players, tablet computers,netbooks, and the like.

Many of these electronic devices include touch screens to allow users tointeract with the electronic devices using touch inputs. While touchinput is an effective way of interfacing with electronic devices in someinstances, in many instances touch inputs are problematic. For example,it may be difficult to use touch inputs when using a device one handed.As another example, when interacting with a device using touch input, auser's finger or stylus typically obscures at least a portion of thescreen.

Additionally, many existing electronic device interfaces are cumbersomeand/or unintuitive to use. User interface controls used to performvarious functions are often esoteric and unintuitive to users. Forexample, UI Pickers are elements of user interfaced used for pickingfrom the end user a value with well-defined type and range. Thesepickers are often part of a mobile UI that requires an input from theuser. One example of such a picker is a number picker which evolved froma simple text field with numerical validation into a virtual spinner.This virtual spinner requires interaction with the user to bring up theinterface and further interaction to correctly select the desired value.

While picking or sliding the control has become much simpler than typingin the value in a mobile device there is still no use of the newlyemerging technology of 3D/Force touch screens. Thus, there remains aneed for new interfaces for electronic devices and techniques forinteracting with such interfaces and electronic devices.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In the following detailed description of the preferred embodiments,reference is made to the accompanying drawings, which form a parthereof, and within which are shown by way of illustration specificembodiments by which the invention may be practiced. It is to beunderstood that other embodiments may be utilized and structural changesmay be made without departing from the scope of the invention.Electrical, mechanical, logical and structural changes may be made tothe embodiments without departing from the spirit and scope of thepresent teachings. The following detailed description is therefore notto be taken in a limiting sense, and the scope of the present disclosureis defined by the appended claims and their equivalents.

This disclosure describes, in part, new electronic devices, interfacesfor electronic devices, and techniques for interacting with suchinterfaces and electronic devices.

For instance, this disclosure describes example electronic devices orcomputers that include a force sensor input and a processor orprocessing elements. In some embodiments, at least one of the forcesensors may be located at or near the display of the electronic device.Using force sensor alone or in combination with one or more othersensors, such as capacitive touch sensors, in some embodiments, theelectronic device allows for simple one-handed or hands-free interactionwith the device. For instance, the device may include one or moreinertial sensors (e.g., gyroscopes or accelerometers), or the like,information from which may be integrated with information from the forcesensor for sensing gestures performed by a user or other combinedinteractions.

This disclosure is addressing a UI element being presented on a devicewhich has the hardware of determining the level of pressure that oneprovides. This can be a tap on a mobile device screen, using digital penor force touch trackpad installed on a laptop. In embodiments, it alsorequires an operating system that provides an API to capture such touchevent and the level of pressure. The hardware to determine the level ofpressure may contain a controller that generates a digitized force valueor other related data. One such example is an iPhone 6s device with iOSoperating system running on it. However, although widely supported iniOS devices this technology can also be found on other device fromdifferent vendors running operating systems such as Android.

FIG. 1 illustrates a system 100 having a 3D touch UI, according to anembodiment of the present invention. The display 120 of the device 110includes a force sensing element 130. The display 120 may also show aninput user interface element 140. The input user interface element 140takes a numerical input from the user. The input user interface element140 may, in embodiments, be a UI picker.

By the term UI picker, user interface elements that their intention isto pick a value from the end user are referred to. The followingdescription demonstrates implementing the essence of using a numberpicker, in an embodiment.

FIG. 2 illustrates a process 200 for a 3D touch U I according to anembodiment of the present invention. In step 210, a touch is detected bythe mobile device. In step 220, a force measurement is obtained. In step230, the user touch is mapped to a UI element and the force measurementchanges the UI element displayed value. The user interface element maybe activated based on the user touch. In step 240, the system determinesthat the force measurement has been held. In step 250, the UI element'svalue is adjusted based on the force measurement.

The implementation of the number picker takes advantage of a touch eventthrown by the operating system to the application view controller forthe picker when a user touch is detected. The user touch may be mappedto the particular UI element. The picker controller is able to accessthe following information through touch events.

1. The location on the screen where the touch event occurred. Thecontroller handles events only occurred within the graphical area of thepicker.

2. The maximum allowed force as it may vary between types of hardware,although fixed for a specific hardware (predetermined by the system, notuser-specific)

3. The force value of the current touch event.

4. The normal force value for an average touch with no intention toprovide force (predetermined by the system, not user-specific). In iOS,for instance, the information for location, maximum and force are allpart of the event object thrown by the iOS to the view controllers.

The range of numbers that can be picked by the picker must be relativelynarrow. Such a narrow range can be mapped into the range between normaltouch force value and maximum available force value. The number ofelements within the numbers range can then determine the force valueranges for each number.

The range of force value for each picker element can be calculated byusing the following calculation.

Define MAX as the maximum possible force value and it is a constantprovided by the operation system. For instance, this value on iPhone 6Sis 6.66666667.

Define NORMAL as the normal force of touching the screen withoutproviding a force and it is a constant provided by the operation system.For instance, this value on iPhone 6S is 1.0.

Define NUM as the number of picker elements.

Calculate the minimum range value of the n-th picker element to beR1=NORMAL+(MAX−NORMAL)*(n−1)/NUM

Calculate the maximum range value of the n-th picker element to beR2=NORMAL+(MAX−NORMAL)*n/NUM

The range for the n-th picker element will therefore be any force valuegreater than or equal to R1 and less than R2.

For instance, in the iPhone 6S the maximum available force value is6.66666667. The normal touch force value is 1.0.

If the numbers picker needs to allow the user to pick an integer valuebetween 1 and 5 (i.e. 1,2,3,4 or 5) then the force quantity values canbe binned as binned force quantities. The force values ranges for thebinning will be as follows.

Value of 1 will match a force value greater than or equal to 1 and lessthan 2.133.

Value of 2 will match a force value greater than or equal to 2.133 andless than 3.266.

Value of 3 will match a force value greater than or equal to 3.266 andless than 4.4.

Value of 4 will match a force value greater than or equal to 4.4 andless than 5.533.

Value of 5 will match a force value greater than or equal to 5.533.

Although the change in force sensitivity defines the value picked by theforce picker, actually picking a value is a result of applying the samelevel of force for some period of time, i.e. a consistent hold.Therefore a time counter will begin counting the amount of time passedsince entering one of the ranges above. If the timer will hit apredefined period of time (e.g., 1 second) the currently matching valuewill be picked and the parent of the UI element will be notified aboutthe picked value (i.e., 1 to 5 in the example above). The UI element maybe modified based on the value. The predefined period of time can rangefrom any values, but will typically be between 0.5 and 2 seconds.

While this description mainly discusses the case of a number picker,this mechanism can also be applied to other types of pickers such assliders. A similar process may be used to control a webpage. The forcemeasurement may be applied to the user interface element to scroll thepage based on that force measurement. For example, a higher forcemeasurement may indicate to scroll further or faster.
